Proteus pneumonia

Proteus is a common species of normal intestinal flora. The main infections related to humans are Proteus ordinary and Proteus mirabilis, which can cause urinary tract infections and abdominal postoperative incision infections, causing pneumonia rare. Exact incidence statistics. Community infections are rare, accounting for 3.4% to 5.8% of nosocomial infections. Similar to other Gram-negative pneumonias, mainly Proteus colonized by inhalation of the oropharynx. Normal people rarely carry this bacterium. In elderly people, the use of antacids or H2 receptor blockers leads to increased gastric juice pH, poor personal hygiene, and gastrointestinal surgery. Proteus colonization of the oropharynx increases. When the body's resistance decreases and the amount of inhaled bacteria is large and the virulence is strong, pneumonia occurs.
